Xyris grandiceps

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Xyris grandiceps faces severe threats from habitat destruction due to agricultural expansion and urban development in its restricted range. Mining activities and infrastructure development have fragmented the remaining suitable wetland habitats where this yellow-eyed grass species occurs. Climate change poses additional risks through altered precipitation patterns that could dry up the seasonal wetlands essential for its survival.

Threat summary

Habitat

Xyris grandiceps inhabits seasonal wetlands, marshy areas, and the edges of temporary pools in tropical and subtropical regions. This yellow-eyed grass species requires specific hydrological conditions with periodic flooding and drying cycles typical of ephemeral wetland systems.
